Considering the power of even a modest modern box, couldn't it be argued that it's a trivial savings? Especially when it would allow more printers to work in raw mode via IPP. Just a thought.
I bumped it up to 4k in mime.types on my main print server, and there seems to be no noticeable load difference. The server in question is neither beefy, nor under a small load. It's a VM running CentOS 5.2, CUPS 1.2.x, with 70 printers, and a daily average of just under 3000 print jobs. Admittedly about one third of those print jobs are barcodes.
